Is Food Addiction a Specific Feature of Individuals Seeking Dietary Treatment from Nutritionists?

Objective: Food addiction (FA) is a condition characterized by excessive and dysregulated consumption of high-energy food, and impulsivity. The diagnostic and nosological framework of FA is still controversial. Therefore, this study aimed at exploring the prevalence of FA in patients seeking help from nutritionists for weight loss, along with its relationship with eating habits, in a pool of 842 participants of both sexes. Method: Eating habits and FA were assessed by, respectively, a self-administered questionnaire and the Yale Food Addiction Scale (YFAS). Statistical analysis included Chi-square for categorical variables, independent t tests to investigate continuous variables and an univariate logistic regression analysis to determine potential risk factors for FA. The relationship between FA diagnosis and potential risk factors was assessed through a stepwise logistic regression model, controlling for age, sex, and body mass index (BMI) classes. Results: Our results indicate that a prevalence of FA in our sample was 15.3%, with no difference between women and men. A higher prevalence was recorded in overweight subjects or obese. According to the YFAS criteria, women were more likely to report a persistent desire and withdrawal than men. Patients with FA compared with those without it, reported a greater number of attempts to lose weight, to self-dieting, a different mealtime repertoire, and to nibble continuously throughout the day. Moreover, the amount of carbohydrates ingested in the same meal seems to represent an eating habit significantly associated with FA. Conclusions: Taken together, our findings show how patients seeking help from nutritionists may display some peculiar features of FA. In spite of its diagnostic controversies, it is evident that FA may play a role in obesity and may also be a feature of some psychopathological conditions. Therefore, it should be more deeply investigated and possibly specifically targeted with tailored therapeutic interventions.

Food addiction and psychiatric comorbidities: a review of current evidence.

BACKGROUND: Food addiction (FA) is characterised by the consumption of appetible foods and by addictive psychological and behavioural symptoms such as cravings, tolerance, limited control of substance intake and withdrawal symptoms. Despite previous research on FA has been hindered by the lack of a formal definition for this condition, recent global trends have stirred the interest of the scientific community towards a proper classification and construct of FA. More specifically, recent studies have pointed towards shared defective neurobiological mechanisms as well as frequent comorbidities between FA, eating disorders, mood disorders, anxiety disorders and substance-related and addictive disorders. OBJECTIVE: In this review, we will provide an overview of the complex symptomatology of food addiction evaluating its relationship with mood disorders, anxiety disorders, eating disorders and substance-related and addictive disorders. METHODS: We wrote a systematic review and followed a PRISMA methods. RESULTS: Patients with FA and substance use disorders show similar risk factors, neurobiological and hormonal correlates, personality traits and symptom profiles. The presence of FA appears to be directly proportional to the burden of symptoms of affective disorder. The comorbidity between FA and other eating disorders is associated with worse clinical conditions and symptoms. CONCLUSION: FA should be considered a sort of transnosological construct existing in different psychopathological domains that have similarities with substance-related, affective, and eating disorders. Furthermore, FA seems to be likely an important factor related to several psychopathological dimensions, but further studies are needed to clarify this view.

Post-traumatic stress disorder in train crash survivors in Italy: the role of mood spectrum dysregulations and intrusiveness.

BACKGROUND: To explore relationships among post-traumatic stress disorder (PTSD), depressive spectrum symptoms, and intrusiveness in subjects who survived the crash of a train derailed carrying liquefied petroleum gas and exploded causing a fire. METHODS: A sample of 111 subjects was enrolled in Viareggio, Italy. AMOS version 21 (IBM Corp, 2012) was utilized for a structural equation model-path analysis to model the direct and indirect links between the exposure to the traumatic event, the occurrence of depressive symptoms, and intrusiveness. Subjects were administered with the SCID-IV (Structured Clinical Interview for DSM-IV), the Questionnaire for Mood Spectrum (MOODS-SR)-Last Month version, the Trauma and Loss Spectrum Questionnaire (TALS-SR), and the Impact of Event Scale-Revised version (IES-R). RESULTS: Sixty-six (66/111; 59.4%) subjects met SCID-IV criteria for PTSD. Indices of goodness of fit were as followed: χ2/df = 0.2 P = .6; comparative fit index = 1 and root mean square error of approximation = 0.0001. A significant path coefficient for direct effect of potential traumatic events on depressive symptoms (ß = 0.25; P < .04) and from depressive symptoms to intrusiveness (ß = 0.34; P < .003) was found. An indirect effect was also observed: standardized value of potential traumatic events on intrusiveness was 0.86. The mediating factor of this indirect effect path was represented by depressive symptoms. Potential traumatic events explained 6.2% of the variance of depressive symptoms; 11.8% of the variance of intrusiveness was accounted for traumatic event and depressive symptoms. CONCLUSIONS: Path analysis led us to speculate that depression symptoms might have mediated the relationship between the exposure to potential traumatic events and intrusiveness for the onset of PTSD.

Decision-Making, Impulsiveness and Temperamental Traits in Eating Disorders.

OBJECTIVE: To explore decision-making, impulsiveness and temperamental traits in patients suffering from eating disorders (EDs), as compared with healthy controls (HC). METHOD: Fifty-one patients affected by ED (fourteen with anorexia restricting subtype, AN-R; fourteen with bulimia, BN; thirteen with anorexia bingeing/purging subtype, AN-BP; ten with binge-eating disorder, BED) and twenty-eight HC. The patients, recruited at the Section of Psychiatry of the University of Pisa (Italy, were evaluated with a battery of neuropsychological questionnaires, including the IOWA Gambling Task (IGT), the Barratt Impulsiveness Scale (BIS-11), the Temperament and Character Inventory (TCI), the Frontal Assessment Battery (FAB) and the Hamilton Depression Rating Scale (HAM-D). RESULTS: The results indicated that AN-R, AN-BP and BN patients showed poorer IGT performances than HC (p < .05), while BED performances were similar to those of HC. IGT scores suggested the existence of similarities in decision-making performances of AN-BP and BN patients, as they performed differently from HC starting from block 3 (F(16.2)=1.7). In addition, differences between AN-BP/BN and AN-R patients were detected, given that they performed differently starting from block 4. As far as BIS-11 is concerned, AN-BP and BN patients reached the highest BIS total scores, when compared with the other groups. Further, they shared similar temperamental and impulsiveness profiles, as demonstrated by their BIS-11 'motor impulsiveness' scores, and by their TCI 'novelty seeking', 'reward dependence' and 'persistence' dimensions. The post-hoc analyses revealed that both AN groups (namely, AN-R and AN-BP) scored significantly lower than HC on the FAB. No patients fulfilled the criteria for the diagnosis of a current major depression. CONCLUSIONS: Decision-making deficits are common in EDs. In AN-R these seem related to cognitive styles, while in AN-BP and BN patients with temperament features and impulsiveness traits.

Food addiction: is it a nosological category or a psychopathological dimension? Preliminary results of an Italian study.

Background Food addiction (FA) is a controversial concept, denoting the craving for certain foods. Given the little information available, the aim of this study was to evaluate the possible relationships between FA and full-blown and subthreshold psychopathology or eating behaviors in subjects consulting nutritional biologists. Materials and methods Three-hundred and fifty subjects completed the following self-questionnaires: Yale Food Addiction Scale (YFAS), Structured Clinical Interview for Mood Spectrum, Self-Report, Lifetime Version (MOOD-SR-LT), Symptom Checklist-90-Revised (SCL-90-R), Structured Clinical Interview for Anorexic-Bulimic Spectrum, Self-Report, Lifetime Version (ABS-SR-LT). Results Most of the subjects were women (n = 278) and the remaining were 72 men. A large proportion of the subjects (77.1%) had a YFAS score <3 and 22.9% ≥3, with no difference between men and women. The YFAS scores ≥3 were significantly and positively related to the all ABS-SR-LT domains, as well as to three dimensions (Depression, Hypomania, Rhythmicity) of the MOOD-SR-LT, and some SCL-90-R domains (Sensitivity, Psychoticism, General Symptom Index and Positive Symptom). Conclusion Our data, while indicating that FA is related to different subthreshold psychopathological domains, in particular, with both depressive and manic symptoms, as well as with rhythmicity of mood spectrum, or with eating subthreshold symptoms, would suggest that it might be a dimension underlying different conditions or symptom clusters.

Mood spectrum comorbidity in patients with anorexia and bulimia nervosa.

PURPOSE: To investigate the presence of mood spectrum signs and symptoms in patients with anorexia nervosa, restricting subtype (AN-R) or bulimia nervosa (BN). METHOD: 55 consecutive female patients meeting DSM-IV criteria for eating disorders (EDs) not satisfying DSM-IV criteria for Axis I mood disorders were evaluated with the Lifetime Mood Spectrum Self-Report (MOODS-SR) and the Mini-International Neuropsychiatric Interview (MINI). The MOODS-SR explored the subthreshold comorbidity for mood spectrum symptoms in patients not reaching the threshold for a mood disorder Axis I diagnosis. MOODS-SR included 161 items. Separate factor analyses of MOODS-SR identified 6 'depressive factors' and 9 'manic-hypomanic factors'. RESULTS: The mean total score of MOODS-SR was significantly higher in BN than in AN-R patients (97.5 ± 25.4 vs 61.1 ± 38.5, respectively; p = 0.0001). 63.6 % of the sample (n = 35) endorsed the threshold of ≥61 items, with a statistically significant difference between AN-R and BN (39.3 % vs 88.9 %; χ 2 = 14.6; df = 1; p = 0.0001). Patients with BN scored significantly higher than AN-R patients on several MOODS-SR factors: (a) MOODS-SR depressive component: 'depressive mood' (11.2 ± 7.4 vs 16.0 ± 5.8; p < 0.05), 'psychomotor retardation' (5.4 ± 5.6 vs 8.9 ± 3.8; p = 0.003), 'psychotic features' (2.0 ± 1.8 vs 4.1 ± 1.6; p = 0.001), 'neurovegetative symptoms' (5.0 ± 2.6 vs 7.7 ± 1.7; p = 0.001); (b) MOODS-SR manic/hypomanic component: 'psychomotor activation' (4.3 ± 3.6 vs 7.4 ± 3.1; p = 0.002), 'mixed instability' (1.0 ± 1.5 vs 2.0 ± 1.6; p < 0.05), 'mixed irritability' (2.5 ± 1.8 vs 3.7 ± 1.6; p < 0.05), 'inflated self-esteem' (1.1 ± 1.4 vs 2.1 ± 1.6; p < 0.05), and 'wastefulness/recklessness' (1.0 ± 1.4 vs 2.0 ± 1.2; p = 0.009). CONCLUSIONS: MOODS-SR identifies subthreshold mood signs/symptoms among patients with AN-R, and BN and with no Axis I comorbidity for mood disorders, and provides a better definition of clinical phenotypes.

Maternal-foetal attachment independently predicts the quality of maternal-infant bonding and post-partum psychopathology.

PURPOSE: The aim of this study was to evaluate the association of maternal antenatal attachment and post-partum psychopathology, maternal-infant bonding, while checking for antenatal psychopathology, for lifetime psychiatric diagnosis and for the known risk factors for peripartum depression. METHODS: One hundred and six women recruited at the first month of pregnancy (T0) were evaluated with the structured interview for DSM-IV TR (SCID-I) to assess the presence of lifetime psychiatric diagnosis and with the Perinatal Depression Predictor Inventory-Revised (PDPI-R), the Edinburgh Postnatal Depression Scale (EPDS), and the State-Trait Anxiety Inventory (STAI). At the sixth month of pregnancy (T1) and at the first month post-partum (T2), all patients were evaluated with the PDPI-R, the EPDS, the STAI, at T1, with the Maternal Antenatal Attachment Scale (MAAS), and at T2 with the Maternal Postnatal Attachment Scale (MPAS). RESULTS: Multivariate regression analyses showed that maternal-foetal attachment was the variable most significantly associated with postnatal symptoms of depression and anxiety and with quality of maternal-infant attachment. The logistic regression analyses showed that antenatal attachment may predict postnatal depressive and anxiety symptoms (respectively, OR: 0.83 - IC [0.74 - 0.95], p = .005, OR: 0.88 - IC [0.79 - 0.98], p = .02), and the quality of maternal postnatal attachment (OR: 1.17 - IC [1.08 - 1.27], p < .001), also after taking into account the known risk factors for perinatal depression, the sociodemographic variables and lifetime psychiatric diagnosis. CONCLUSION: The quality of maternal-foetal bonding may independently predict the quality of maternal-infant attachment and post-partum depressive and anxiety symptoms. A comprehensive assessment of maternal risk factors for perinatal psychopathology during pregnancy should include the evaluation of antenatal attachment that could be modifiable by specific interventions promoting the quality of maternal bonding.

The Role of Electroconvulsive Therapy (ECT) in Bipolar Disorder: Effectiveness in 522 Patients with Bipolar Depression, Mixed-state, Mania and Catatonic Features.

OBJECTIVE: We evaluated the effectiveness of Electroconvulsive Therapy (ECT) in the treatment of Bipolar Disorder (BD) in a large sample of bipolar patients with drug resistant depression, mania, mixed state and catatonic features. METHOD: 522 consecutive patients with DSM-IV-TR BD were evaluated prior to and after the ECT course. Responders and nonresponders were compared in subsamples of depressed and mixed patients. Descriptive analyses were reported for patients with mania and with catatonic features. RESULTS: Of the original sample only 22 patients were excluded for the occurrence of side effects or consent withdrawal. After the ECT course, 344 (68.8%) patients were considered responders (final CGIi score ≤2) and 156 (31.2%) nonresponders. Response rates were respectively 68.1% for BD depression, 72.9% for mixed state, 75% for mania and 80.8% for catatonic features. Length of current episode and global severity of the illness were the only statistically significant predictors of nonresponse. CONCLUSION: ECT resulted to be an effective and safe treatment for all the phases of severe and drug-resistant BD. Positive response was observed in approximately two-thirds of the cases and in 80% of the catatonic patients. The duration of the current episode was the major predictor of nonresponse. The risk of ECT-induced mania is virtually absent and mood destabilization very unlikely. Our results clearly indicate that current algorithms for the treatment of depressive, mixed, manic and catatonic states should be modified and, at least for the most severe patients, ECT should not be considered as a "last resort".

Longitudinal monitoring of heartbeat dynamics predicts mood changes in bipolar patients: A pilot study.

OBJECTIVES: Recent research indicates that Heart Rate Variability (HRV) is affected in Bipolar Disorders (BD) patients. To determine whether such alterations are a mere expression of the current mood state or rather contain longitudinal information on BD course, we examined the potential influence of states adjacent in time upon HRV features measured in a target mood state. METHODS: Longitudinal evaluation of HRV was obtained in eight BD patients by using a wearable monitoring system developed within the PSYCHE project. We extracted time-domain, frequency-domain and non-linear HRV-features and trained a Support Vector Machine (SVM) to classify HRV-features according to mood state. To evaluate the influence of adjacent mood states, we trained SVM with different HRV-feature sets: 1) belonging to each mood state considered alone; 2) belonging to each mood state and normalized using information from the preceding mood state; 3) belonging to each mood state and normalized using information from the preceding and subsequent mood states; 4) belonging to each mood state and normalized using information from two randomly chosen states. RESULTS: SVM classification accuracy within a target state was significantly greater when HRV-features from the previous and subsequent mood states were considered. CONCLUSIONS: Although preliminary and in need of replications our results suggest for the first time that psychophysiological states in BD contain information related to the subsequent ones. Such characteristic may be used to improve clinical management and to develop algorithms to predict clinical course and mood switches in individual patients.

Trait- and pre-sleep-state-dependent arousal in insomnia disorders: what role may sleep reactivity and sleep-related metacognitions play? A pilot study.

OBJECTIVE: Research into the cause of chronic insomnia has identified hyperarousal as a key factor, which is likely to have both trait and state components. Sleep-related cognition, metacognition, and sleep reactivity also play an important role in insomnia. Our aim was to investigate how these insomnia-related constructs are associated with trait predisposition and pre-sleep arousal in subjects with an insomnia disorder. METHODS: Fifty-three individuals with insomnia disorder (according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (F = 33; 52 + 10)) and 30 healthy controls (F = 18; 51.8 + 12 years) were evaluated with a set of questionnaires, including the Ford Insomnia Response to Stress Test (FIRST), Metacognition Questionnaire - Insomnia (MCQI), Arousal Predisposition Scale (APS), and Pre-sleep Arousal Scale (PSAS). Statistical analyses included multiple regression to elucidate the independent determinants of APS and PSAS. RESULTS: Participants with insomnia presented higher FIRST, MCQI, APS, PSAS scores (p-values <0.001) than healthy controls. In insomnia, APS and cognitive PSAS were best determined by MCQI (respectively, B = 0.09, p = 0.001, B = 0.08, p = 0.02), somatic PSAS by cognitive arousal (PSAS B = 0.35, p = 0.004) CONCLUSIONS: This study suggests that in insomnia disorders, trait predisposition toward hyperarousal and pre-sleep-cognitive-state-dependent arousal may be closely related to sleep-related metacognitive processes. Sleep-related metacognitive processes may be associated with trait hyperarousal within the framework of a mutual relationship, and could, in turn, modulate cognitive pre-sleep-state arousal. A broad range of cognitive and metacognitive processes should be considered when dealing with subjects with insomnia.

Association between stress-related sleep reactivity and cognitive processes in insomnia disorder and insomnia subgroups: preliminary results.

OBJECTIVE: Stress-related sleep reactivity, sleep-related cognitions, and psychological factors play an important role in insomnia. The aim was to investigate their possible association in Insomnia Disorder, insomnia subgroups, and healthy subjects. METHODS: The cross-sectional study consisted of 93 subjects who met diagnostic criteria for Insomnia Disorder according to Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) and of 30 healthy subjects. Survey instruments included the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Ford Insomnia Response to Stress Test (FIRST), Dysfunctional Beliefs about Sleep scale (DBAS), Beck Depression Inventory (BDI), and Zung Self-Rating Anxiety Scale (SAS). Descriptive statistics, Pearson correlations, χ(2)-test, and multiple linear regression were performed. RESULTS: FIRST and SAS best determined the insomnia subjects vs good sleepers (FIRST χ(2) = 109.6, p <0.001, SAS χ(2) = 120.3, p <0.001). FIRST was best predicted by DBAS (p <0.001), PSQI (p <0.001), and SAS by PSQI (p <0.001), ISI (p <0.05), BDI (p <0.001). In the sleep onset subgroup FIRST was related to ISI, PSQI, and DBAS and in the combined subgroup with DBAS. In both subgroups SAS was related to PSQI, ISI, and BDI. CONCLUSIONS: Findings suggest potential implications: (1) among the factors that may contribute to insomnia, stress-related sleep reactivity, and psychological factors, such as anxiety symptoms, may distinguish insomnia subjects from good sleepers; (2) sleep reactivity and sleep-related cognitions seem interrelated, unhelpful beliefs may affect the stress reactivity; (3) psychological factors may influence sleep quality and the severity of insomnia; (4) these important sleep-related variables may have similar associations in insomnia subgroups; they may constitute the core factors for insomnia development and maintenance.

Relationship between insomnia symptoms, perceived stress and coping strategies in subjects with arterial hypertension: psychological factors may play a modulating role.

OBJECTIVE: The aim of the study was to evaluate perceived stress and coping strategies in people with hypertension, according to the presence of insomnia symptoms and by using a set of variables that included anxiety and depressive symptoms evaluation. METHODS: A total of 371 hypertensive patients were enrolled during their first visit to the Hypertension Outpatient Unit. The Perceived Stress Scale (PSS), Brief-COPE, Insomnia Severity Index (ISI), Beck Depression Inventory (BDI), Self-rating Anxiety Scale (SAS), and State-Trait Anxiety Inventory (STAI) were administered. Patients with other sleep disorders or with incomplete data (n = 41) were excluded. RESULTS: Data from 330 hypertensive patients were analyzed (males 51%, mean age 57 ± 13 years). Those with insomnia symptoms (n = 70, 21%) were older (p = 0.02), more frequently females (p = 0.01), and presented with higher PSS (p < 0.001), BDI (p < 0.0001), SAS (p = 0.0003), and STAI (p < 0.0001) scores than those without insomnia symptoms. In a linear regression trait, anxiety (p < 0.0001) and depressive symptoms (p < 0.05) were independent predictors of high PSS. Patients with insomnia symptoms showed lower scores in coping strategies, such as positive reframing (p = 0.03) and emotional support (p = 0.04), and an increased score in behavioral disengagement (p = 0.03). Trait anxiety and insomnia severity were independent predictors of less effective coping strategies. CONCLUSIONS: People with hypertension and insomnia symptoms showed higher perceived stress and less effective coping strategies than non-insomniacs; psychological factors such as trait anxiety and depressive symptoms may play a modulating role in these relationships. Prevention and treatment of insomnia symptoms and psychological factors should receive high attention for people with hypertension.

Association Between Stress-Related Sleep Reactivity and Metacognitive Beliefs About Sleep in Insomnia Disorder: Preliminary Results.

To evaluate the relation between stress-related sleep reactivity and metacognitive beliefs about sleep in subjects with insomnia disorder (93) and in a group of healthy controls (30) a set of variables, including Ford Insomnia Response to Stress Test (FIRST) and Metacognition Questionnaire-Insomnia (MCQ-I), have been used. Internal consistency of the Italian version of FIRST was studied. Univariate correlation, regression analysis, and principal component analysis were also performed. The Italian version of FIRST showed good internal consistency and discriminant validity. Sleep reactivity was higher in women (p < .05) and correlates positively in both genders with metacognitive beliefs about sleep (p < .01) in insomnia. In insomnia, metacognitive beliefs may play a key role in modulating sleep reactivity. Therapeutic strategies acting selectively on metacognition to reduce stress-related sleep reactivity in insomnia may be useful.

Multiple phenotypes of resting-state cognition are altered in insomnia disorder.

BACKGROUND: Research has supported the role of cognitive processes in the development and maintenance of insomnia, yet a standardized characterization of mind-wandering experiences in insomniacs is lacking. OBJECTIVES: The aim was to understand the quantitative nature of thoughts and feelings during mind wandering in insomniacs and healthy controls and their relationship with sleep-related parameters. METHODS: We used the 5-minute eyes-closed wakeful rest as an experimental model condition of mind wandering. Forty-seven individuals with insomnia disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (48.66±15.62 years; 31 women) and 29 healthy controls (50.66±15.14 years; 17 women) participated in the experiments and completed the Amsterdam Resting-State Questionnaire (ARSQ) immediately after the resting session. Participants also completed the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), the Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS). Statistical analyses included multiple regression to elucidate the independent determinants of ARSQ phenotypes. RESULTS: Participants with insomnia presented higher ISI, PSQI, and DBAS scores than did healthy controls. Insomniacs had strikingly different scores on most dimensions of the ARSQ, in particular Discontinuity of Mind, Self, Sleepiness, and Health Concern, that correlated positively with ISI and DBAS. Multiple regressions highlighted that for insomniacs, ISI was the best predictor of both Discontinuity of Mind and Health Concern. CONCLUSIONS: Resting-state activity in insomnia is altered and it seems to be related to unhelpful beliefs and insomnia severity. Resting-state neuroimaging in combination with the ARSQ could reveal important associations between these aberrant cognitive scores and their underlying systems-level brain mechanisms.

Psychopharmacological options for adult patients with anorexia nervosa.

The aim of this review was to summarize evidence from research on psychopharmacological options for adult patients with anorexia nervosa (AN). Database searches of MEDLINE and PsycINFO (from January 1966 to January 2014) were performed, and original articles published as full papers, brief reports, case reports, or case series were included. Forty-one papers were screened in detail, and salient characteristics of pharmacological options for AN were summarized for drug classes. The body of evidence for the efficacy of pharmacotherapy in AN was unsatisfactory, the quality of observations was questionable (eg, the majority were not blinded), and sample size was often small. More trials are needed, while considering that nonresponse and nonremission are typical of patients with AN.

Catatonia in 26 patients with bipolar disorder: clinical features and response to electroconvulsive therapy.

OBJECTIVES: We describe the clinical characteristics and short-term outcomes of a sample of inpatients with bipolar disorder with severe catatonic features resistant to pharmacological treatment. METHODS: The study involved 26 catatonic patients, resistant to a trial of benzodiazepines, and then treated with electroconvulsive therapy (ECT). All patients were evaluated prior to and one week following the ECT course using the Bush-Francis Catatonia Rating Scale (BFCRS) and the Clinical Global Impression (CGI). RESULTS: In our sample, women were over-represented (n = 23, 88.5%), the mean (± standard deviation) age was 49.5 ± 12.5 years, the mean age at onset was 28.1 ± 12.8 years, and the mean number of previous mood episodes was 5.3 ± 2.9. The mean duration of catatonic symptoms was 16.7 ± 11.8 (range: 3-50) weeks, and personal history of previous catatonic episodes was present in 10 patients (38.5%). Seventeen (65.4%) patients showed abnormalities at cerebral computerized tomography and/or magnetic resonance imaging and neurological comorbidities were observed in 15.4% of the sample. Stupor, rigidity, staring, negativism, withdrawal, and mutism were observed in more than 90% of patients. At the end of the ECT course, 21 patients (80.8%) were classified as responders. The BFCRS showed the largest percentage of improvement, with an 82% reduction of the initial score. The number of previous mood episodes was significantly lower and the use of anticholinergic and dopamine-agonist medications was significantly more frequent in non-responders than in responders. CONCLUSIONS: Our patients with bipolar disorder had predominantly retarded catatonia, frequent previous catatonic episodes, indicating a recurrent course, and high rates of concomitant brain structure alterations. However, ECT was a very effective treatment for catatonia in this patient group that was resistant to benzodiazepines.

Italian validation of the Sleep Condition Indicator: A clinical screening tool to evaluate Insomnia Disorder according to DSM-5 criteria.

STUDY OBJECTIVES: The present study investigated the validity, reliability and, as novel aspects, the temporal stability and discriminant validity of the Italian version of the Sleep Condition Indicator (SCI), a new brief tool to appraise Insomnia Disorder (ID) according to the new criteria of the DSM-5. METHODS: Subjects with ID (DSM-5), Obstructive Sleep Apnea Syndrome (OSAS) (ICSD3) and a group of healthy subjects (H) were recruited. At the first evaluation (T1), SCI, the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI) were administered. ID patients also completed the SCI 2months later (T2). Statistical analyses included Cronbach's alpha co-efficient calculation, Intraclass Correlation, Receiver Operating Characteristic (ROC) curves and Pearson correlations. RESULTS: Eighty-eight ID (n=50 F, mean age 49.9±15.1 years), 43 OSAS (n=22 F, mean age 50.2±9.1 years) and 40 H (n=22 F, 49.3±13 years) were recruited at T1. SCI, PSQI and ISI scores were significantly higher in the ID group vs H and OSAS (both p<.001). ROC analysis revealed cut off of >18 to correctly identify 100% of H, cut off of >17 the 100% of OSAS and <17 the 100% of ID. Cronbach's alpha were 0.71 at T0, 0.78 at T2 for ID, 0.76 and 0.81 respectively for H and OSAS. SCI showed a negative correlation with ISI (p<.01) and PSQI (p<.05). CONCLUSION: The Italian version of SCI shows good internal consistency, temporal stability and concurrent validity in insomnia, confirming data on the original version. Importantly, the present study shows that the SCI effectively discriminates insomnia from both normal sleep and OSAS.

Efficacy and tolerability of paliperidone ER in patients with unsatisfactorily controlled schizophrenia by other antipsychotics: a flexible-dose approach.

This study evaluates the effectiveness of paliperidone ER in patients with symptomatic but not highly acute schizophrenia in terms of efficacy, safety, and patients' perception of their social functioning and well-being. This is a multicenter, open-label prospective study with a flexible-dose approach; 133 patients were enrolled and followed for 13 weeks after switching to paliperidone ER. Outcome efficacy measures were as follows: the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression-Severity (CGI-S) scale, and the Personal and Social Performance (PSP) scale; in addition, the Subjective Well-being under Neuroleptics (SWN-20) scale, the Drug Attitude Inventory (DAI-30), and the sleep evaluation scale were used. Symptom Rating Scale (ESRS), adverse events, and subjective side effects were recorded. 118/133(88.7%) patients completed the study. The mean PANSS score decreased (88.98 ± 10.09 to 66.52 ± 16.29; P < 0.001); 40.5% of the patients achieved improvement of at least 30%. PSP and CGI-S scores as well as DAI-30 and SWN-20 decreased (P < 0.001). ESRS (P < 0.001) decreased significantly from the baseline. Throughout the trial, no deaths occurred and only one serious adverse event was reported. Paliperidone ER has proved to be efficacious, safe, and well tolerated also with this approach more closely resembling actual clinical practice. Patient-relevant outcome parameters such as social functioning and quality of life improved, which is crucial for treatment adherence in clinical practice.

Electroconvulsive therapy in catatonic patients: Efficacy and predictors of response.

Recent evidence favors the view of catatonia as an autonomous syndrome, frequently associated with mood disorders, but also observed in neurological, neurodevelopmental, physical and toxic conditions. From our systematic literature review, electroconvulsive therapy (ECT) results effective in all forms of catatonia, even after pharmacotherapy with benzodiazepines has failed. Response rate ranges from 80% to 100% and results superior to those of any other therapy in psychiatry. ECT should be considered first-line treatment in patients with malignant catatonia, neuroleptic malignant syndrome, delirious mania or severe catatonic excitement, and in general in all catatonic patients that are refractory or partially responsive to benzodiazepines. Early intervention with ECT is encouraged to avoid undue deterioration of the patient's medical condition. Little is known about the long-term treatment outcomes following administration of ECT for catatonia. The presence of a concomitant chronic neurologic disease or extrapyramidal deficit seems to be related to ECT non-response. On the contrary, the presence of acute, severe and psychotic mood disorder is associated with good response. Severe psychotic features in responders may be related with a prominent GABAergic mediated deficit in orbitofrontal cortex, whereas non-responders may be characterized by a prevalent dopaminergic mediated extrapyramidal deficit. These observations are consistent with the hypothesis that ECT is more effective in "top-down" variant of catatonia, in which the psychomotor syndrome may be sustained by a dysregulation of the orbitofrontal cortex, than in "bottom-up" variant, in which an extrapyramidal dysregulation may be prevalent. Future research should focus on ECT response in different subtype of catatonia and on efficacy of maintenance ECT in long-term prevention of recurrent catatonia. Further research on mechanism of action of ECT in catatonia may also contribute to the development of other brain stimulation techniques.
